Specification of To ZZ whom-fit 'may concern.'

Be it known that I7 @RNAN S. Coon, a citizen Oi the United States7 residing at Fitchburg, in the county of lVorcester and State of Massachusetts, have invented a new and use'tul Shook Holder, ot which the Vollowing is a specification.

This invention relates to a device for holding matched boards in position for forcing them together to produce box sides and ends tor use in the manufacture oi'` boxes.V lthough the invention is capable ot use for matching lumber and for other purposes than making boxes,4 this is the principal use forwhich it is intended.

The principal objects oit the invention are to provide a simplev and convenient support 'for the above mentioned purpose which will accurately hold. the boards in position and prevent their buckling while they are being matched; to provide simple and convenient means ior 'forcing the clamping devices into n position to prevent this buckling action; and

to improve and simplify the various features ot' the device.

Reference is to bc had to the accompanying drawings in whichW Fig. 1 is a plan oit a shook holder con structed in accordance with this invent-ion;

Fig. 2 is a front elevation;v

Fig. 3 is an end elevation; and

Fig. 4i is a sectional view on the line wat o't Fig. 3 on enlarged scale.

The device is designed to support a plurality ot' boards 10 which are tongued and grooved at their edges. For this purpose it involves an inclined trame consisting of two legs 12 at the opposite ends oi" the holder and a plurality o't supports 13 located between them and havingtheir front surfaces parallel with them. This whole structure iforins an inclined supporting trame for the boards. These parts 12 and 13 are held together by bottom and top cross pieces 1d. The legs 12 are adapted to rest on the floor and the structure is supported in inclined position by rear legs 16 also inclined and tixed to the upper ends of the legs 12 and held together by a horizontal cross piece 17 at the bottom. f

The two legs 12 are provided with a supporting plate 20 located near the bottom for receiving the bottoms ot' the boards 10. This is shown in the form ot an angle bar, the up- SHOCK HOLDER.

which are capable ot swinging on horizontal axes to bring this bar down into clamping position. This bar 21 is preferably anangle iron or otherwise made to have an L-shaped cross section.

23 arepivotedsat both endsv and can move trom the dotted line position shown in Fig. 3 to the Yfull line position.` Pivotally' mounted on. a rod 25 which entends acrossbetween N the legs 16 is a lever 26 having a treadle 27 on its end projecting forward of the front legs 12.

Forthe purpose of guiding the clamping bar 2i l have shown a metal guide 30 iixed to the leg i2 on which this bar is movable. y

In the use oit the device t-he boards are placed with their edges horizontal and resting on the support formed ot the members 12 and 15S. The bottom one rests on the pate 2O at its lower edge, and the others extend across horizontally as indicated. The ends ot these boards are of course brought into alignment and into a position in which the inwardly extending tlange on the bar 21 projects over them. lWhen the parts are in this position the operator steps on the treadle 2T which brings down the clamping bar 21 so that is edge holds the edges ot the boards and prevents buckling. Then the boards are matched by forcing them together in the usual way by pounding on a strip Ot wood applied to the upper edge ot the series ot boards or shook or by screw pressure it desired.

.lt will be seen that the device simply holds the ends ot the boards and keeps them from buckling and getting out ot alignment whie they are being forced together in the usual way and constitutes a convenient support for them during this operation.

Although I have illustrated and described only a single torni ot the invention I am aware ot the tact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore I do not wish to be limited to all-,the details of construction herein shown and described, but what I do claim is l. In a shook holder, the combination of a y support for holding a series of matched boards in inclined position, with means carried by said support and movable on it toward and from its shook supporting surface for clamping one end of the shook in a flat condition and preventing their buckling while they are being assembled.

2. In a shook holder, the combination of a frame comprising an inclined support for the boards of the shook, a movably mounted clamp of L'sha}`ied` cross section having a flange extending over the ends of all Vthe boards ywhen so supported and a flange for guiding it at theedge of the support, and means or moving sald flange into a position to `beer upon the fiat surface of said boa-rds vand hold them in position.

`3. In a shook holder, the combination of a 'framecomprising front-legs and rear legs located at convergin angles, the front legs constituting an inc ined support for the boards ofthe shook, a movably mounted clamp havinga flan e extending overl the -cnds oi the shook W en so supported and movable toward and from into a position to bear upon the fiat surface of said shook and ,support for the shook, a clamp mounted along the edge of said support and having a flange adapted to engage the front side of said shook. a link connected with said clamp, aguide for guiding the clamp to move in a plane at right angles to the front surface of the shook, a treadle, Aand links connected to said treadle for drawing down. the clamp when the treadle is depressed,

5. In a shook holder. the combination of a frame constituting an inclined support tor the boards of the shook, a movablyv mounted clamp having a flan e extending over the end of the shook Wien so supported and movable toward and from and into a posi tion to bear upon the fiat surface of said shook and hold it in position, means for operating the clamp comprising a pair of Alinks pivoted together, and means for drawingvthe linksdown to Vforce the clamp inwardly.

In testimonyA whereof I have hereuntoaixed myV signature.
